Bleeding was seen in the tympanic cavity, mastoid air cells, internal auditory meatus and facial nerve canal. Bleeding was observed in the scala tympani, cochlear aqueduct and endolymphatic sac, but there were no fractures. In the other patient, bleeding was seen in the internal auditory meatus and facial nerve canal. In the right ear, endolymphatic hydrops was observed in all turns of the cochlea.
